Broadly, embodiments of the inventive concepts disclosed herein are directed to a touchscreen fuel panel that enables checklist automation. In embodiments, the fuel panel includes a touchscreen display and a controller coupled to the touchscreen display. The controller is configured to generate a graphical user interface at the touchscreen display and receive user inputs via the touchscreen display. The controller is further configured to execute an automated set of fuel management checklist procedures in response to a user input. In some embodiments, the controller can be alternatively or additionally configured to execute other automated sets of checklist procedures, for example, pre-flight, in-flight, taxi/takeoff/landing (TTL), and/or post-flight procedures.

Referring to FIG. 1 , an environmental view of an aircraft cockpit 100 including an exemplary embodiment of a touchscreen fuel panel 102 is shown. Existing aircraft environments include hard switches (e.g., toggles, knobs, flip switches, slide switches, etc.) for managing fuel in the aircraft. A touchscreen fuel panel 102 replaces existing hard switches, and is integrated within the center console or elsewhere in the aircraft environment so that it is conveniently accessible to flight crew.

Referring to FIG. 2 , a perspective view of a touchscreen fuel panel 102 according to an exemplary embodiment is shown. The touchscreen fuel panel 102 is a self-contained device in data communication with other on-board avionics systems to receive and display data on a touchscreen display 200. The touchscreen display 200 allows users to interact with the connected systems, including through the execution of stored procedures. In at least one embodiment, the touchscreen display 200 employs glass resistive touch that may be glove compatible. The touchscreen fuel panel 102 includes an enclosure 202 that holds, carries, and/or is coupled to various electronic components of the touchscreen fuel panel 102. For example, the enclosure 202 can hold, carry, and/or be coupled with a touchscreen display 200, a controller or processor, memory, and one or more communication interface ports.

Referring to FIG. 3 , a block diagram of a system 300 for implementing a touchscreen fuel panel according to an example embodiment is shown. The system 300 includes a controller 302 in data communication with a touchscreen 304 and a memory 306 for storing processor executable code. The controller 302 populates the touchscreen 304 with a graphical depiction of an aircraft fuel system.

In at least one embodiment, the system 300 includes an interface device 308 in data communication with the controller 302; such interface device 308 may comprise Ethernet, ARINC-429, RS-232, or other similar protocols. The interface device 308 allows the controller 302 to interact with avionics systems to retrieve real-time data for display and send instructions to those avionics systems. Furthermore, the controller 302 may query the avionics systems via the interface device 308 to determine an architecture of the fuel system (numbers of tanks, pumps, valves, etc.). The controller 302 may then create a graphical representation of the fuel system as it actually exists. The controller 302 may also query the avionics systems to determine acceptable status boundaries for the depicted systems and store those status boundaries in the memory 306.

The controller 302 provides processing functionality for at least the touchscreen fuel panel 300 and can include any number of processors, micro-controllers, circuitry, field programmable gate array (FPGA) or other processing systems. In at least one embodiment, the controller 302 is in data communication with a data storage element for storing checklist procedures and checklist results when such procedures are executed. The controller 302 can execute one or more software programs embodied in a non-transitory computer readable medium (e.g., memory 306) that implement techniques described herein. The controller 302 is not limited by the materials from which it is formed or the processing mechanisms employed therein and, as such, can be implemented via semiconductor(s) and/or transistors (e.g., using electronic integrated circuit (IC) components), and so forth.

The memory 306 can be an example of tangible, computer-readable storage medium that provides storage functionality to store various data and/or program code associated with operation of the controller 302 and touchscreen 304, such as software programs and/or code segments, or other data to instruct the controller 302, and possibly other components of the touchscreen fuel panel 300, to perform the functionality described herein. Thus, the memory 306 can store data, such as a program of instructions for operating the touchscreen fuel panel 300, including its components (e.g., touchscreen display 304, controller 302, interface device 308, etc.), and so forth. It should be noted that while a single memory 306 is described, a wide variety of types and combinations of memory (e.g., tangible, non-transitory memory) can be employed. The memory 306 can be integral with the controller 302, can comprise stand-alone memory, or can be a combination of both. Some examples of the memory 306 can include removable and non-removable memory components, such as random-access memory (RAM), read-only memory (ROM), flash memory (e.g., a secure digital (SD) memory card, a mini-SD memory card, and/or a micro-SD memory card), solid-state drive (SSD) memory, magnetic memory, optical memory, universal serial bus (USB) memory devices, hard disk memory, external memory, and so forth.

The interface device 308 can be operatively configured to communicate with components of the touchscreen fuel panel 300. For example, the interface device 308 can be configured to retrieve data from fuel sensors, pumps, valves, actuators, other aircraft sensors and/or actuators, the flight management system, and/or any other aircraft controllers or data sources, transmit data for storage in the memory 306, retrieve data from storage in the memory 306, and so forth. The interface device 308 can also be communicatively coupled with the controller 302 to facilitate data transfer between components of the touchscreen fuel panel 300 and the controller 302. It should be noted that while the interface device 308 is described as a component of the touchscreen fuel panel 300, one or more components of the interface device 308 can be implemented as external components communicatively coupled to the touchscreen fuel panel 300 via a wired and/or wireless connection. The touchscreen fuel panel 300 can also include and/or connect to one or more input/output (I/O) devices (e.g., via the interface device 308), such as the touchscreen 304, another input device (e.g., a mouse, a trackball, a trackpad, a joystick, a line select device, a touchpad, a keyboard, a keypad, a microphone (e.g., for voice commands), etc.), another output device (e.g., a speaker, a display, a status light, etc.), and so forth. In embodiments, the interface device 308 includes or is coupled to a transmitter, receiver, transceiver, physical connection interface, or any combination thereof.

In at least one embodiment, the controller 302 may be configured to present requested information such as pump status, fuel status, valve status, engine manifold status, etc., and/or generate a control signal for at least one fuel system component via the interface device 308 in response to receiving a user input representing a user interaction with the touchscreen 304.

Referring to FIG. 4 , a screen 400 displayed by a touch screen fuel panel according to an exemplary embodiment are shown. The touchscreen fuel panel described herein provides status feedback for manifold, pump, and valve control which can be automated and result in status summary for operators (e.g., pilots or other flight crew). For example, pump, valve, fuel quantity, and probe accuracy may be checked prior to takeoff and periodically during a flight. The graphical user interface (GUI) presented by the touchscreen fuel panel adds situational awareness and provides flight crew with fuel system status information. Furthermore, a centralized, computerized, GUI based system allows for automation of complex tasks with a graphical representation of the step-by-step execution of those tasks.

In at least one embodiment, the GUI includes a pump menu 446 (e.g. Boost Pump Menu), system valves 412, 414, 416, 418, 420, 422, 424, 426, 438, pump status indications 440, 442 (e.g., Pump Status icons, animations, highlighting, and/or color indications), fuel quantity indications for each fuel reservoir 404, 406, 408, 410, 448 (e.g., fuel quantity indications associated with schematic representations of the fuel reservoirs), and fuel calculations 444 (e.g., transfer fuel quantity, total fuel quantity, etc.). The GUI may further include additional features, such as a transfer quantity reset button 450, a fuel dump button 452 which may be guarded with specific access requirements such as a password/passkey, user authentication, or multi-factor authentication, or any other status/control icon, button, or text box that is selectable and/or configured to display status information. In at least one embodiment, a crew member may interact with various components of the fuel system, including additional functions of those components such as through fuel pump boost menus 446. Furthermore, the screen 400 may receive and display real-time status information pertaining to those components and other components that may not be directly addressable such as fuel lines 430 and fuel calculations 444. For example, during normal operations, a processor may update, in real-time, a graphical depiction of one or more system valves 412, 414, 416, 418, 420, 422, 424, 426 may be transitioned from a closed state to an open state; fore fuel pumps 440 and aft fuel pumps 442 may be animated to depict when such fuel pumps 440, 442 are actually operating.

In at least one embodiment, components in operation are rendered with a visual indication. For example, fuel reservoirs 404, 406, 408, 410 may be rendered in a different color while the corresponding fuel pumps are operating. Furthermore, fuel lines 428, 430 may be rendered in a different color corresponding to fuel functions within the manifold. In at least one embodiment, the fuel lines 430 may also be rendered with a graphical representation of fuel flow; for example, with moving or animated dashed lines to indicate a flow direction. Likewise, the speed of such moving dashed line may correspond to a flow rate. Fuel flow through particular system valves 412, 414, 416, 418, 420, 422, 424, 426 may be indicated by extending the graphical representation of the fuel lines 428, 430 to the implicated system valve 412, 414, 416, 418, 420, 422, 424, 426, including color delineations of the fuel functions.

In at least one embodiment, complex or composite tasks that require sequential operation of various components 412, 414, 416, 418, 420, 422, 424, 426, 438, 440, 442, 446 may be programed, or a stored procedure retrieved, and executed via a controller which also graphically depicts the execution of each task and any feedback corresponding to those tasks in real-time. Components 412, 414, 416, 418, 420, 422, 424, 426, 438, 440, 442, 446 may be rendered in distinct colors to indicate success or failure of a particular task. Furthermore, components 412, 414, 416, 418, 420, 422, 424, 426, 438, 440, 442, 446 may be rendered in a color or style indicative of routine or periodic component failure based on historical task execution status.

In at least one embodiment, one or more components 412, 414, 416, 418, 420, 422, 424, 426, 438, 440, 442, 446 may represent assemblies of sub-components. Where any sub-component is active, the graphical representation of the corresponding components 412, 414, 416, 418, 420, 422, 424, 426, 438, 440, 442, 446 may indicate such activity. Selecting the corresponding component 412, 414, 416, 418, 420, 422, 424, 426, 438, 440, 442, 446 may cause the controller to render a graphical representation of the assemblage of sub-components and allow individual sub-components to be interacted with, or status information corresponding to individual sub-components.

In at least one embodiment, a fuel management system including a touchscreen panel is conduction cooled. The system may employ AFD-3200 device architecture, include a NVIS Filter, support D-Zus rail installation, and/or support DAL A functionality. The touchscreen fuel panel 100 may meet DO-160G qualification and comply with DO-254 artifacts. The fuel management system may support DO-178 platform software, ARINC 661 display graphics rendering, ARINC 661 toolkit, and/or local and remote A661 graphics.
